How do I merge these SELECT statements...

Hi guys,

I have the following two SQL statements...

SELECT Task.Task_Name, SUM(Logged_Time.Time_Spent)
FROM (Logged_Time INNER JOIN Task ON Task.Task_ID =
Logged_Time.Task_ID)
GROUP BY Task.Task_Name

SELECT Task_BU.Task_ID, Business_Unit.BU_Name, Task_BU.Split
FROM (Business_Unit INNER JOIN Task_BU ON Business_Unit.BU_ID =
Task_BU.BU_ID),
(SELECT MAX(Task_BU.Date) AS Last_Date FROM Task_BU GROUP BY
Task_BU.Task_ID)
WHERE Task_BU.Date = Last_Date

These are from a task management system. I want to multiply
SUM(Logged_Time.Time_Spent) from the first statement by Task_BU.Split
from the second statement but I can't figure out how to combine the
statements together. I have tried a few combinations but Access always
wants me to put all the select items (Task_Name, BU_Name, Split etc) in
the GROUP BY clause and this doesn't give me the results I want.

Basically all I want in the SELECT line is...

SELECT Task.Task_Name, Business_Unit.BU_Name, Task_BU.Split *
SUM(Logged_Time.Time_Spent)

So that I can multiply the splits for each task with the total time
logged against the task.

Thanks in advance...

Lyndon.

well, if you work with your two posted SQL statements as separate queries,
and use them as the base of a third query, the following might work:

change the first query to

SELECT Task.Task_ID, Task.Task_Name, SUM(Logged_Time.Time_Spent)
FROM (Logged_Time INNER JOIN Task ON Task.Task_ID =
Logged_Time.Task_ID)
GROUP BY Task.Task_ID, Task.Task_Name

now you have a Task_ID field in each base query. see if the third, "linking"
query will return what you need if you link the two base queries on their
Task_ID fields.
